PRESSED STEEL HUB Filed May 1, 1931 y im Patented Jan. 31, 1933 UNITED STATES PATENT ori-ICE i CHARLES R. STOUGH, OF LANSING, MICHIGAN, ASSIGNOB MOTOR WHEEL CORPORA- TION, 0E LANSING, MICHIGAN, A CORPORATION 0F MICHIGAN rnnssnn STEEL HUB Application led lay 1, 1931. Serial No. 534,186.

The object of the present invention is .the provision of a hub structure embodying lightness, strength and economy of manu.

facture from standpoints of labor, machine operations and material.

Instead of forging and machining from a bar or billet, I utilize rolled sheets and, by punching and pressing operations, form two tubular hub-portions of the same or dis' similaz diameters, flange one endl of each hub particuv either both outwardly or both inwardly or one outwardly and the other inwardly. I then place the flanges insurface contact and weld; thus producing a unitary hub structure with the axle-receiving barrel portion of uniform or non-uniform diametric section and contour and with external radial flange for mounting the wheel body,- all at a minimum expense of labor and material, both light and strong.

In order that the inventlon may be readily understood, two embodiments of the same are set forth in the accompanyin drawing and in the description predicated t ereon, by way of illustration.

In the drawing Fig. 1 is a diametric section through one form of hub structure embodying the invention; and

Fig. 2 is a similar view of another form of construction.

Having particular reference to Fig. 1, an annular plate is by suitable pressing, drawin and punching operations formed into a tuular portion 11 and a radially-extending iianged portion 12 suitably apertured locally at 13 for the recept-ion of securing bolts or rivets by which the completed hub structure may be attached to a wheel body.

A second plate is by an appropriate drawing operation formed into a tubular portion 14 having an inturned iange 15 about an axial opening 16.

The two tubular members thus formed are placed in axial alignment with their flanged portions in surface contact, preferably along the root of the iianges, and are permanently welded together as at 17.

Either before or after forming and attaching, the barrel portions 11 and 14 of the hub structure are locally indented inwardly as at 18 and 19 and provide internal abutments at 20 and 21 for the bearing liners 22 and 23.

Referring now to Fig. 2 of the drawing, a modified construction 1s shown wherein an annular plate, by pressing, drawing and punching operations is formed into a tubular portion 24 and a radially-extending flanged portion 25 provided with bolt or rivet-receiving apertures at 26, and a second plate is by appropriate operations formed into a tubular portion 27 with la radially-extending anged portion 28 with bolt apertures 29.

The tubular barrel portion 24 and the tubular barrel portion 27 are inwardly indented at 30 and 31 to provide internal abutments 32 and 33 for the bearing liners 34 and 35.

The Vtwo barrel portions thus formed are placed in axial ahgnment with their outturned flanges 25 and 28 in surface contact and with the apertures 26 and 29 in register. They are then secured together by spot welding at intervals as indicated at 36.

I claim:

l. A hub structure comprising front and rear tubular barrel portions arranged end to end in abutting xedly attached relation,

one of the abutting ends expanded and the other contracted to form respectively an outwardly projecting wheel-attaching flange and an inwardly projecting stiifening ange in a common transverse plane.

2. A hub structure comprising front and rear tubular barrel portions of dissimilar diameter arranged end to end, the smaller end expanded to form an outwardly projecting v the front portion expanded to form an out wardly projecting wheel-attaching flange and the adjacent end of the rear portion contracted to form an inwardly projecting stiffenin angethe twolmgesoecupyn lubstantlly coxhmon plxnes, the ends providin abutting convex faces an xedly attached y welding.

In testimony whereof I have hereunto subscribed*y my name.`
